Remove len and is_empty from impl_array_newtype macros 

An array in Rust has no concept of length, it is a fixed size data type.
Equally an array cannot be "empty", again since it is a fixed size data
type. These are methods/concepts seen in slices and vectors.

Remove the `len` and `is_empty` methods.
